Demo of Microsoft AirSim with PX4

From the video description:

I wanted to put this video together to share what I've been working on as it relates to PX4 simulation. I've been really impressed with the capabilities of AirSim and I hope this video makes it a little easier to understand. You can learn more about AirSim here: https://github.com/microsoft/AirSim and my GitBook notes can be found here: https://droneblocks.gitbook.io/airsim... To learn more about DroneBlocks please visit: https://www.droneblocks.io Please feel free to leave a comment below if you have any questions and I hope to share more information in the near future. Thanks for watching.

Quick install BatMon v4 released

8467210494?profile=RESIZE_710x

BatMon v4 released
One of the main challenges faced with BatMon was the installation overhead. Installing BatMon v3 took over an hour on a new battery pack. Second challenge was the cost overhead of a BMS system on each battery. We have reduced these issues significantly with the BatMon v4 release.
  • v4 is super fast to install on most batteries with a tool, and connects to the balance leads.
  • The modular board make it possible to reuse BatMon after end of life of a battery. The XT90 leads can be replaced if they are worn, but can practically be reused few times, reducing the cost overhead on each smart battery pack.

Clever research from ETH showing how it uses the drone camera to maintain position while a quadcopter spins to maintain control after one motor fails. 

From DroneDJ:

Researchers at the University of Zurich and the Delft University of Technology have been able to keep a drone flying after a motor fails. The researchers have managed to use onboard cameras to keep the test drones in the air and flying safely.

 

AD

 

team of researchers has come up with a simple yet ingenious way to solve a problem that will usually result in a drone falling to the ground due to a motor failure.

Well, motor failures don’t often happen, but when they do, the drone needs to stay in the air regardless, especially if people are nearby or the drone is being used for a commercial job. Redundancy is important when it comes to drones.

Davide Scaramuzza, head of the Robotics and Perception Group at UZH and of the Rescue Robotics grand challenge at NCCR Robotics, shared:

When one rotor fails, the drone begins

Unmanned aerial vehicles, also known as drones, are small aircrafts that don’t have a human pilot onboard that can either operated remotely or automated and travel with the help of GPS coordinates. They are made of light material to reduce weight, which enables them to fly at high altitudes. Drones are controlled by a ground cockpit and can easily return to their marked starting position in case of low battery or when the drone loses contact with

An agricultural robot also referred to agri-robot, is a robot designed and deployed for agricultural purposes. Agriculture robots automate the farming process which is repetitive and time-consuming. The agriculture drones are unmanned aerial vehicles operated by controllers over the farmland. The agricultural robots and drones are used in agricultural applications like spraying fertilizer and pesticides, cloud seeding, planting seeds, harvesting, crop growth, and farmland monitoring as well as soil analysis. 

The agricultural sector across the globe is experiencing transition by replacing and changing the traditional framing processes and equipment. The implementation of automated farming equipment like agriculture drones and robots is facilitating the farming business for earning greater profits by adding analytical decision methods and autonomous operations.

According to the research report from Facts and Factors, the global agricultural robots and drones market in 2019 was approximate

The main focus of this research is to develop a real-time forest fire monitoring system using an Unmanned Aerial Vehicle (UAV). The UAV is equipped with sensors, a mini processor (Raspberry Pi) and Ardu Pilot Mega (APM) for the flight controller. This system used five sensors. The first is a temperature sensor that served to measure the temperature in the monitored forest area. The others sensors are embedded in the APM. There are a barometer, Global Positioning Sensor (GPS), inertial measurement unit (IMU) and compass sensor. GPS and compass are used in the navigation system. The barometer measured the air pressure that is used as a reference to maintain the height of the UAV. The IMU consists of accelerometer and gyroscope sensors that are used to estimate the vehicle position. The temperature data from the sensor and the data from GPS are processed by the Raspberry Pi 3, which serves as a mini processor. The results of the data processing are sent to the server to be accessible onli

The main focus of this research is early detection system for forest fires by using Unmanned Aerial Vehicle (UAV). Data source of fires are collected by mobile devices such as GPS-equipped UAV quadcopter, non-contact infrared sensor, and the sensor stabilizer. The data from sensor is sent via telemetry link 433 Mhz, towards the Ground Control Station. Then the data is processed by a program that has been made, namely SPTA Real-time v0.1.0, which can show the temperature data as well as the color layer based on the difference of temperature levels in real-time on a digital map layer. The coordinates of fires are observed by SPTA realtime v0.1.0, and then it is compared with the coordinates of the source of the fire that is recorded manually. The results of data retrieval, the area that monitored is 3662 m2, constant height of 30 m, quadcopter speed of 5 m / s. First Data, with wind speeds of 3.2 m / s has a difference of 1.18 m from the coordinate source of the fire, within GPS toleranc

Long Range

I left the tittle wide open intentionally.  This is something that is beyond my skills.  One of the things that we all struggle with.  If you want two cameras, you have to have two transmitters or switch betwen them.  Telemetry from your autopilot, can get some of that from the OSD butr to update the autopilot, you need another tranciever  that you can also use for telemetry sometimes.  Then you need the reciever for the remote control stuff.  OK Thats two transmitters, one transciever that really doesn't have good range and a reciever.  All of this back and forth is data.  Some analog some digital.  What I am hoping to throw into the hornets nest here is an idea that I'm hoping the community can take and run with it.  What I'm proposing is using 802.11n  Not g or ac but n.  Reason, most of the wireless service providers are using n to distribute their product, internet connection.  With n you have a range that is in quite a few miles with excellent bandwidth. An 802.11n tranciever can

Object tracking demo on VTOL

5612486892?profile=RESIZE_710x

It is essential to lock and track the target that you are trying to monitor when you are conducting an aerial surveillance task through the fixed-wing plane or VTOL because your camera can quickly lose the target if it is not tracked. Luckily more and more drones are applying this feature. This video shows how we realized this through an affordable and easy to use solution. Please check this video to learn more: https://youtu.be/MrZkVPpl9nY

Anyway, please comment if you have better solutions.
